How to wire a trailer electric brake controller?

I'm planning on installing the BMW Class III hitch and wire harness on my new F15, but I'm trying to figure out how to wire in a electric brake controller. I know the E70's did not have a pre-wired connector for a controller - does anyone know whether they added that for the F15, because it would certainly make this project a bit easier. I've seen some articles on wiring a controller for the E70 which involves making a splice into a light control module behind the glove box - this is to get a 12 volt source for brake light status. If the F15 does not have a pre-wired connector for a brake controller then I suppose the process would have to be similar, but is it identical? Any advice on how to do this would be appreciated.

Later E70 models did have a brake controller prewire, I just don't think it was there on the first few years of E70 production. Since the F15 is built on the E70 platform, there is a good chance it is just the same. Dealer will probably have to confirm, since I don't think any have done it and posted yet.

Here is some background on what to look for in prewiring. If your vehicle has the four wire plug in the rear quarter panel, looks like it will be straightforward.

The attachment below may be helpful. It is the instructions for the BMW trailer brake controller kit. I think it was a Prodigy P2. Not sure if it is still available, or if it is available for the F15, but could be helpful background info.

Let us know how it goes.

Thanks for the info, and especially the installation insructions for the E70. I will call my dealer later today to see if BMW NA supports this same type of installation for the F15.

Turns out the F15 uses the same installation for the brake controller as the E70 - they run a cable from the connector behind a panel in the right rear of the truck up to the driver-side cup holder, which is where they put the controller. I'm going to have the dealer install the Class III Hitch and brake controller.

Also available is a wireless unit that I purchased and am very happy with. Plugs into your accessory outlet.
